Kuwait Is Awash in Oil Money. But It Can’t Keep the Power On.
The Persian Gulf nation has instituted rolling blackouts to cope with surging summer electricity demand, stirring frustration among citizens.

"But in June, as soaring temperatures strained the country’s electrical grid, a Kuwaiti elementary school teacher, Shaikha al-Shammari, found herself leading lessons in the dark when the power suddenly cut out. Last month, she went home to find her own children struggling to cope after the electricity went out there, too, shutting off the air-conditioning."

Sunamp’s thermal battery uses a chemical found in salt-and-vinegar potato chips

"At the heart of Sunamp’s thermal battery are three compounds: sodium acetate trihydrate (SAT), a food flavoring used in salt-and-vinegar potato chips; water; and a sprinkling of so-called crystal habit modifiers. SAT has been used for years in hand warmers, which are prepared by heating the substance until it dissolves into a supersaturated solution. When triggered, SAT recrystallizes, giving off heat in the process."
